This invention relatesto printingapparatus and more particularly to the hand operated variety adapted for printing monetary values and other protective legends upon bank checks and similar negotiable instruments. The eflectiveness of such protective legends depends largely upon the use of a suflicient quantity of ink to impregnate the paper and render the impression indeli-- A ble and hence the efiiciency of apparatus of this character requires full inking of the type before each impression is made. One object of the present invention therefore is to provide a machine of this character having an improved inking means of a simple, reliable and efiective construction for insuring full inking of the type forms preliminary to. each impression of the same upon the paper. A further object is to provide in combination with such means a simple and. practical construction for feeding the work after each impression is made.

To these and other ends the invention-resides in certain improvements and combina .35 parts, however, in the position which they occupy while making an impression;

Figure 4 a sectional view on the line 43-4 in Figure 2, and

' Figure 5 is an enlarged perspective 'viewof arts of the feeding mechanism detached. imilar reference numerals throughout the several views indicate the same parts.

' The invention is embodied in the present instance, by way of illustration, in a printing apparatusor checkwriting machine comprlsing'a frame having a lower or base'portion 10, Figures 1 and 2,.on which is sup-' ported an upper casing portion 11. Between these portlons 1s an inwardly extending-work receiving slot 12 above a work bed 5 13 on thebase on which the work is'placed. to receive the impression. The upper portion 11 of the casing carries in the present instance a rotary type wheel having on its periphery a plurality of type forms adapted to be brought by rotation of the wheel selectively to printing position above a platen in the base 10 which is raised to press the work against the type by. operating. means comprising a handle 14, the latter-op crating also a feeding mechanism for fee ing the work between successive im ressions.

' The platen is preferably in the orm of a metal block 15 having an upper im ression surface 16 which, like the faces of t e type,

is. preferably ridged or corrugated to scarify the paper as an incident to the impression of the same to promote absorption of andimpregnation by the ink to render the impresslon indelible. The platen is secured in any suitable manner in a slot .17 in the forward end of a platen lever 18 pivotally supported intermediate its ends-on a shaft 19, the ends of which latter are mounted in the sides of the base 10.

The operating means forefiecting the relative impressing movement of the type wheel and platen comprises, in the present instance, a toggle mechanism formed by a pair of links 20 and 21 pivotally connected with o each other as at 22, link 20 being pivotally connected with the rear end of the platen lever at 23. The toggle link 21 is fixed on a shaft 24 rocking in hearings in the sidesof frame portion 11 and projecting through gg one side of the same for the attachment thereto of the operating handle 14. A spring 25 tends to maintain the handle raised and the platen lowered ready for the insertion ofthe work. 1 no The printing wheel is shown at 26 as fixed on a shaft 27 rotating in bearings at its ends in the sides of frame portion 11 through which one end of the shaft projects and carries an operating knob 28. The periphery 06 of the wheel is provided with a plurallty of of type forms 29 spaced circumferentially about the same for. cooperation individually The inking means comprises preferably an inking roll 33 rotatably mounted on a.

spindle 34 carried by an arm 35 pivotally mounted on a spindle 36 on a bracket 37 fixed on a cover plate, 38 on the frame. A spring 39 presses the ink roll toward the type wheel so that it lies in the path of rotation of the type forms at a point spaced as shown from the printing position over the platen. Cover plate 38 is pivotally supported on a spindle 40 and closes an opening in the top of the frame through which the ink roll is raised for reinking when the cover is swung back on its pivot.

Means are provided in' conjunction with the ink roll for insuring contact therewith of each type form selected for printing as an incidentto the impression of the same, whether it beimpressed one or a number of times in succession. Such means comprises, preferably, a plurality of cam slots 41 formed in one end on the'printing wheel,

one slot corresponding to each of the type forms. Cooperating with these slots is a follower 42 in the form of a pin or roller carried on the forward end of a' member or arm 43. The latter is arranged for movement upon each actuation of the operating means, being in the present instance formed integrally with the upper toggle link 21. These parts are so constructed and arranged that while the type wheel is left freely rotatable to select the type forms, such selection by means of the indicating device already described brings the selected type form into contact with or just above the inking roll Subsequent operation of handle 14 to impress the same on the work causes arm 43 to swing downwardly,

whereby its follower 42 engages the corresponding cam slot in the type wheel and swings the latter so that the selected type form is moved from contact with the inking roll direct into printing position above the platen, before the latter rises above the printing bed. Upon release of handle 14 after the impression, the parts return to the 'position shown in Figure 2 and the type wheel is in the present instance swung back to the previously selected position. Subsequent impression of the same or a different character is accompanied by the automatic inking of thesame inthe same manner prior to each impression.

The present invention provides in combination with the above features a simple and effective means for feeding the work between successive impressions o erated by the impressing movement of the platen; Rotatably mounted at its ends in a bracket 44 on the base is a spindle 45 carrying a pair of feed rolls 46 projecting slightly through openings in the printing bed for engagement with the underside of the work which is held in contact with the feed rolls by a presser roller 47 rotatably carried on a spring actuated clip 48 pivotally mounted on the upper portion 11 of the frame for manual operation in the usual manner to release the work. The forward feed roll 46 carries a ratchet wheel 49 with forwardly projecting teeth or studs 50. Engaging with the latter is a pawl 51 in the form of an angular leaf spring, one end of which is secured to a bracket 52 fixed to the forward underside of the platen lever. .The bracket carries also a stop 53 for preventing overthrow of the feed rolls. It is apparentfrom this cpnstruction that when the platen is raised to make an impression, the free end of the pawl is advanced idly to engage one of the teeth of the ratchet wheel and as theplaten descendsthe pawlis lowered, thereby moving the ratchet wheel and the feed rolls through a predetermined distance for effecting the desired feeding movement of the work. At the end of each movement of the feed rolls and ratchet wheel the tooth of the latter en-' gaged by the pawl is 'brought against a rearwardly projecting finger 54 on'stop 53 'to prevent overthrow. While the pawl is raised "for the next operation, however, the stop 53 is raised with it and its finger 54 clears the ratchet wheel tooth so as not to interfere with the movement of the same. As the feeding movement terminates, finger 54 drops back to position across the pathof' the succeeding tooth to limit its movement.

The operations of the various parts of the apparatus have been described in detail in connection with the construction of the same and may be summarized as follows: The workhaving been located in the desired position on the printing bed to receive the first character of the impression or legend and being held by the Presser roller 47, knob 28 is rotated to bring the dollar aplurality of tion of said I handle then raises the platen through the printing bed so that it presses the work from below against the selected type form above. Upon release of the handle the .parts are restored to position by spring 25,

the type wheel being returned to the previously selected position ready for a second impression of the same or a difierent symbol. In this way a protective legend representing any, desired monetary value may be completed on the work. Each operation of handle 14 as described also accomplishes feeding coaction of ratchet wheel 49 and pawl 51 to rotate the feedrolls 46 to advance the work step by step to receive sucimpression and hence the operation of the machine at maximum efliciency with the maximum degree of protection afiordedby its use. Furthermore, the eflicient impression of the work in this manner and the feeding of the same betwe en impressions are accomplished by mechanism. of asimple compact and reliable character having obvious advantages from the point of view of manufacture and maintenance.
